A gas meter diaphragm is formed from liquid injected silicone rubber, with an integral annular bead that permits its attachment to a pan assembly without retaining rings or adhesives. By using liquid injected silicone rubber, the gas meter diaphragm can be molded rather than cut from a material sheet, allowing the diaphragm to have integrally formed retaining rings or other physical features that require varying thicknesses of material.
